User space Video4Linux (UV4L)

UV4L was originally conceived as a modular collection of Video4Linux2-compliant, cross-platform, user space drivers for real or virtual video input and output devices (with absolutely no external difference from kernel drivers).

• Installation for ARM (Raspberry Pi)
  • installed uv4l using stretch version => raspicam works
  • raspian buster not yet available
• v4l2rtspserver

Raspidisp driver

• turn a given Raspberry Pi HDMI output source into a virtual Video4Linux-compliant device (such as a camera) that can capture the images coming from that source
• when used with the Streaming Server, it allows your Raspberry Pi to be mirrored and controlled from the browser (plugin-free). demo

uv4l-server

To run the ‘raspicam’ driver with the streaming server enabled on port 9000 and a password for the admin user (in one line):
